## Symmetrical Optimum

Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides firstĀ order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude optimum discussed in the previous…

## Uncompensated Large Time Constants

Uncompensated Large Time Constants: It is possible to compensate only one Uncompensated Large Time Constants using a PI controller. A PID controller is used to compensate for two large time constants. On technical grounds, compensation…

## Phase Margin Optimum

Phase Margin Optimum: The method can be based on the phase margin in which the controller is designed to provide a minimum phase margin. The design makes use of Bode plots. The ratio of time…

## Magnitude Optimum

Magnitude Optimum: The design of a controller based on the principle Magnitude OptimumĀ that it allows all the freĀ­quencies to pass through in a similar way for a simple system is shown in Fig. 6.31. The…

## Controller Design Frequency Response

Controller Design Frequency Response: The Controller Design Frequency Response (or root locus) alters or reshapes the frequency response (or root locus) of the original system to the desired one. Thus the ideal goal of compensation…
